Ingredients
  

  • 1 lb ground beef
  • 1 large onion thinly sliced
  • 8 slices rye bread
  • 4 slices Swiss cheese
  • 4 slices cheddar cheese
  • butter for grilling
  • salt and pepper to taste
  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon sweet pickle relish
  • 1 teaspoon Worcestershire sauce

Instructions
 

  • In a small bowl, combine mayonnaise, ketchup, sweet pickle relish, and Worcestershire sauce to make the secret sauce. Set aside.
  • In a large skillet, melt 1 tablespoon of butter over medium heat. Add the sliced onions and cook, stirring occasionally, until caramelized, about 15–20 minutes. Remove and set aside.
  • Divide ground beef into 4 equal portions and shape into thin patties. Season both sides with salt and pepper.
  • Cook patties in the same skillet over medium-high heat until cooked through, about 3–4 minutes per side. Remove and set aside.
  • Butter one side of each slice of rye bread. Place 4 slices, butter-side down, on a skillet or griddle over medium heat.
  • Top each with a slice of Swiss cheese, a cooked patty, caramelized onions, a slice of cheddar cheese, and another slice of bread, butter-side up.
  • Cook until the bread is golden brown and the cheese has melted, about 2–3 minutes per side.
  • Remove from the skillet and let rest for 1 minute. Slice in half and serve immediately with the secret sauce on the side or drizzled over the top.

Notes

For an extra indulgent touch, toast the rye bread lightly before assembling. You can also swap out Swiss or cheddar for provolone or pepper jack for a twist.
